Influence of a power-weight ratio of a forest train on speed mode and fuel economy

When designing a logging truck it is necessary to rationally select a tractor and a timber drug bearing in mind the truck load related to the engine power of the tractor. The studies presented in the article demonstrate the diversity and interdependence of the factors that determine the regularities of average speed and fuel consumption variations in real conditions. This inevitably leads to the conclusion that the minimum value of fuel consumption factors for various types of engines and road trains should be determined experimentally.
